The AirTAC GFR60020MLF2K AirTAC Filter Regulator 3/4 in PT is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60020MLF2K is a size-600 GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the 3/4 in PT-threaded port size, with a manual drain bowl in aluminium alloy, a 40 um standard filter element, a low-pressure regulator type, an embedded square gauge reading in psi, and a reverse/check valve fitted. Maximum working (inlet) pressure is 1.0 MPa (145 psi), with an operating temperature range of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types, 40 um or 5 um (W) filter grades, gauge scales and G/NPT thread options. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

On a finishing line where spray equipment needs a gentle, stable supply pressure, this low-pressure-type filter regulator cleans the air of water and particulate and holds the set pressure at the guns, with the psi gauge giving a direct read at the station.
Feeding carton sealers, case packers and wrapping machines on a packaging line, this 3/4 in unit conditions the plant air and regulates it to the cylinders and actuators, while the check valve holds the downstream circuit if supply pressure drops.
At the inlet of a pneumatic control panel or manifold serving multiple circuits, this filter regulator provides one conditioned, regulated take-off point, with the included bracket for panel mounting and the manual drain for scheduled bowl service.
Size and port set the capacity: the 600 series with a 3/4 in PT port is the step to take when your line needs more flow than the 200/300/400 sizes serve, but the right check is the flow curve against your demand, not a single rating. This unit carries a manual drain, so an operator opens the bowl drain periodically; choose automatic or differential-pressure drain codes if you want condensate removal without that routine. The 40 um element suits general air preparation; specify W for the 5 um grade where finer filtration is needed. The square gauge here reads in psi; MPa and bar scales are available, and an external round gauge is optional. PT is the standard thread; G (BSPP) and NPT are order options. A mounting bracket is included, and the K code means a reverse/check valve is fitted.
Because flow is published as curves and this is the low-pressure regulator type, ask us to confirm the adjustment range and sizing against your application before ordering.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves, not as a single rated number, so we do not quote a figure here. Tell us your line pressure and air demand and we will confirm the flow curve and sizing from the datasheet on request before you order.
The M in the code means the condensate bowl is drained by hand on a scheduled basis; automatic (A) and differential-pressure drain versions are available if you prefer unattended draining. The trailing K means a reverse/check valve is fitted, so downstream pressure is held if the upstream supply drops.
